Mushroom Potato Soup

• 1 onion, peeled
  
• 4-5 potatoes, peeled and cubed
  
• stronger dried or fresh mushrooms (agaricus campestris ), rinsed and chopped
  
• 2 tablespoons of oil
• 2 tablespoons of flour
• 7-9 cups of water, salt
• sweet Hungarian paprika
• parsley or bay leaves

Boil the onion, potatoes, and mushrooms in a gently salted pot of water. Prepare the roux (saute flour in oil until a soft reddish brown, add paprika and dilute with a bit of water before adding to soup). Toss in parsley and boil for a few more minutes before serving.

If it is made with bay leaves, add smoked sausages or sauteed chopped bacon and boil for 8 to 10 minutes. In either case, vinegar can be added before serving.
